I think you'll find that you have an excellent defence should they try to take this all the way to court. Jopson v Homeguard [2016] B9GF0A9E is the defence you use. Loading/unloading or delivering is not parking.
Whilst the NtK is not strictly PoFA compliant as it fails on 9(2)(e)(i), it is probably too late to rely on that if you have identified yourself as the keeper to also be the driver. It may have helped you win at POPLA.
For now, you just have to wait and see if/when a Letter of Claim is sent. You can safely ignore all debt collector letters. They are powerless to do anything except try and scare you into paying by using scary words like "bailiff" and "CCJ". They hope you are low-hanging fruit on the gullible tree that'll capitulate and pay up when the pressure builds up.
You may want to inform any customers who have unregulated private parking companies infesting their properties that they will be blacklisted from receiving deliveries if they don't rein in their ex-clamper thugs.
Can you go through POPLA response to me? POPLA response is in an attached pdf file i uploaded in a reply today. In my appeal I wrote this
"Motorist response to operator evidence
• Can I just get an explanation as to how delivery drivers are supposed to
actually do our jobs? It seems extremely predatory and wrong, to give
delivery drivers parking fines when we're obviously there temporarily. Had
there of been signs of where buildings names are, I would have been in and
out within 10 minutes, and I would have been within the 10 minute grace
period. I do not think it's right or fair to fine delivery drivers at all. Please can
I just get some leniency and receive a goodwill gesture? I will never work and
deliver at this location again, and I will also make it a goal to make sure no
one I work with goes there again. And the land owners can take it up with
their renters as to why they're not receiving their packages at all. Do you see
the problem here? People like me get punished for just doing our jobs, now if
this appeal is rejected, I will be going to all the drivers in our group chat, and
telling them to avoid this location at all cost and just return the packages
back to depot. How is it fair that delivery drivers are punished for doing our
jobs? And that now if this is rejected, the people living there won't get their
packages on time since I will tell everyone to avoid this location. If the land
had signs that state where things are, people like me who are new to the
area, just doing our job will be in and out within 10 minutes and within the 10
minute grace period. Like I said, it's extremely predatory of them to give
PCN's to delivery drivers who are just trying to do their job. If you still think
that I should be punished for doing my job, then please just let me pay the
reduced amount. They're a private parking company, who are abusing the
system to hand out fines to everyone they can, without showing some
goodwill to people with extenuating circumstances, such as delivery drivers.
Is it really fair to you?"
